[OAI-implementers] Extensible Repository Resource Locators (ERRoLs) Service

[Young,Jeff]

I am please to announce the official release of the new Extensible
Repository Resource Locators (ERRoLs) Service for resolving OAI identifiers
in various ways. The ERRoL project page is at
http://www.oclc.org/research/projects/oairesolver/default.htm.

This service can work with any repository registered in the "OAI Registry at
UIUC" that Tom Habing announced recently
(http://gita.grainger.uiuc.edu/registry/). 

For oai-identifiers, the Core ERRoL pattern is this:

"http://purl.org/oai/" + <oai-identifier>

Below is a example of a Core ERRoL. This resolves to a list of Extended
ERRoLs that will return the various types of metadata and content related to
that identifier.

http://purl.org/oai/oai:VTETD:etd-06152001-152749

For repositories that don't use the oai-identifier scheme, the Core ERRoL
pattern is this:

"http://purl.org/oai/" + <repositoryIdentifier> + "/" + <identifier>

For example:

http://purl.org/oai/ndltd.oclc.org/oai:VTETD:etd-06152001-152749

The list of available repositoryIdentifiers can be found at
(http://gita.grainger.uiuc.edu/registry/ListRepoIds.asp?self=1).

Please check out some of the other cool things this service can do by
reading the project page.

Comments and suggestions are welcome.

Jeff
